摘要：
我们研究了归一化矢势在 $a_0=100-200$ 范围内的激光脉冲对自旋极化 ${}^3$He 的无碰撞冲击波加速。2D-PIC 模拟中采用的装置由置于主氦靶前方的固体碳箔组成。该碳箔被激光脉冲加热，并保护氦免受高振荡场的影响。反过来，这会引发具有更均匀场的冲击波，从而产生高极化离子束。我们观察到，在模拟中纳入辐射反作用会带来更高的束流电荷，而不会在显著程度上影响极化度。
英文摘要：
We investigate Collisionless Shock Acceleration of spin-polarized ${}^3$He for laser pulses with normalized vector potentials in the range $a_0 = 100-200$. The setup utilized in the 2D-PIC simulations consists of a solid Carbon foil that is placed in front of the main Helium target. The foil is heated by the laser pulse and shields the Helium from the highly oscillating fields. In turn, a shock wave with more homogeneous fields is induced, leading to highly polarized ion beams. We observe that the inclusion of radiation reaction into our simulations leads to a higher beam charge without affecting the polarization degree to a significant extent.
